1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: Tamsin Mather <tamsin.mather@xxxxxxxxxxxxxx> Postdoctoral Research Assistant in Sulfur Cycling at Subduction Zones University of Oxford - Department of Earth Sciences, Closing date: Noon (UT) Monday 6th January 2020 Provisional interview date: Friday 24th January 2020. This post is fixed-term for up to 24 months. More details and how to apply here: https://www.jobs.ac.uk/job/BWD497/postdoctoral-research-assistant-in-sulfur-cycling-at-subduction-zones Please contact Tamsin.Mather@xxxxxxxxxxxxxx with any questions. The department seeks to appoint a Postdoctoral Research Assistant to work under the direction of Professor Tamsin Mather (University of Oxford) to further our understanding of the sulphur cycle through subduction zones. The role will have a specific focus on making measurements of sulphur contents and isotopes in primitive melt inclusions hosted in mineral phases from volcanoes in key subduction zones. This post is part of the NSF/NERC-funded â??Sulfur Cycling at Subduction Zonesâ?? project, whose principal aim is to understand the sulphur inputs into subduction zones and explore the use of isotopic tracers to further understand the relation of S inputs to that emitted from arc volcanism. This grant is led by Terry Plank (Lamont Doherty Earth Observatory, USA) and involves key collaborations with the University of Palermo, Italy (led by Alessandro Aiuppa) and the Edinburgh Ion Microprobe Facility in the UK amongst others. Subduction zones play a key role in mediating global sulphur processing and the climatic effects of arc volcanism, the economic potential of arc magmas, and the oxidation state of solid Earth reservoirs. Yet, the inputs, processing and recycling of S throughout the subduction system are still poorly constrained. The PDRA will contribute to a significant improvement in our understanding of the S cycle. They will collaborate with colleagues studying subduction zone inputs and take a novel approach to understanding volcanic arc S outputs. This will involve measuring sulphur concentration and isotopic composition in well-studied suites of undegassed olivine-hosted melt inclusions from the same subducting systems targeted by the teams based in the USA and Italy focusing on S inputs. They will be involved in ion microprobe method development and will develop models of S isotope behaviour during magma evolution and degassing. The overall aim is to explore the potential to trace sulphur isotopes from sediment input to arc output. The postholder will be based at the Department of Earth Sciences, University of Oxford, but will spend analytical time at the Edinburgh Ion Microprobe Facility. They will also be required to travel to the USA and Italy for sample selection and preparation and collaborator meetings. This post is full-time and fixed-term for up to 24 months and we wish to fill it at the earliest opportunity. Candidates must hold or be close to completion of a PhD/DPhil in a relevant field, have experience of preparing and analysing melt inclusion samples and/or undertaking ion microprobe analyses, together with an appreciation of volatile processing through subduction zones. Furthermore, the successful candidate must be able to manage their own research and administrative activities, lead and report on an independent research programme and have excellent written and oral communication skills. There is scope for the PDRA to undertake some teaching, either in taught courses, field courses, or in the supervision of Masters projects.
